Postgraduate Study

计划在EOS进行研究生学习的学生应该注意，如果他们在该系和贡献科学:生物学上选修额外的课程，他们可能会提出更强有力的申请, chemistry, computer science, mathematics, and physics. 强烈建议学生就专业设计与教师进行协商，并通过独立研究讨论研究项目的选择, fellowship-funded summer research, and honors projects.

Interdisciplinary Majors

买球平台的跨学科专业与数字和计算研究的坐标专业截然不同, education, and environmental studies. The department does not explicitly participate in formal interdisciplinary programs. However, 地球与海洋科学系和物理系为对物理感兴趣的EOS专业学生确定了主修和辅修课程(EOS主修/物理辅修)。, 对物理专业感兴趣并有EOS应用的学生(物理专业/EOS辅修). 对EOS专业/物理辅修并专注于固体地球学科感兴趣的学生最好选择以下可选物理课程：

对EOS专业/物理副修并专注于地表地球学科感兴趣的学生最好选择以下可选物理课程:

对海洋学专业感兴趣的学生/对海洋学学科感兴趣的辅修物理专业的学生最好选择以下的选修物理课程:

Information for Incoming Students 

买球平台大学的地球与海洋科学系是一个由地球科学家组成的协作社区，他们研究有关地球和气候的基本问题. In our courses and research, 我们通过取样岩石来观察和描述地球和海洋的性质和过程, soils, sediments, shells, ice, and waters. We implement a range of analytical approaches in the classroom, field, and laboratory to study Earth’s systems at all scales. From atoms to oceans, we unravel Earth’s past, understand Earth’s present, and prepare for our future. 

Where to begin?

EOS offers two introductory courses – EOS 1105 Introducing Earth in the fall and EOS 1505 Oceanography in the spring. 这些选项中的任何一个都可以计入EOS专业，并打开中级课程的大门. No placement tests are required.

EOS 1105 Introducing Earth, offered in the fall, 入门课程是针对一年级学生的吗?座位是预留给一年级学生的吗. The course explores the processes that have shaped Earth, such as: plate tectonics, earthquakes, volcanoes, rivers, glaciers, the explosion of life on Earth, and the extraction of natural resources. Classes and weekly labs provide hands-on opportunities to work with the themes of the course. You will apply the skills you’ve learned through collaborative, accessible field experiences along the Maine coast; stream modeling; exploration of our rock, mineral, and fossil collections; and examination and construction of maps, graphs, and images.  

EOS 1505 Oceanography, offered in the spring, 入门课程是否与环境研究交叉列出，并优先给一年级学生注册. The course explores the tectonic evolution of the ocean basins, the record of ocean history preserved in deep-sea sediments, global ocean circulation, waves, tides, ocean ecosystems, and the ocean’s role in climate change. 课程和每周的实验提供了与同龄人合作的实践机会，并通过物理模型探索这些主题, data collection, and computational analysis. You will apply the skills you’ve learned to authentic research projects, including a culminating field-based study of estuaries in the Gulf of Maine.

What’s next?
In upper division courses, 我们提供实践机会，参与与课程主题相关的更高级的合作研究项目. The rocky coastline, local rivers, forests, farms, estuaries, 缅因湾为研究环境和地球系统过程提供了非凡的自然实验室. For example, EOS students learn the skills and knowledge to address questions such as:

• How do energy and materials move among the different parts of the Earth system? How do humans alter these processes from local to global scales? (EOS 2005 Biogeochemistry: An Analysis of Global Change)
• What controls the global distribution of Earth’s natural resources? (EOS 2020 Earth, Ocean, and Society)
• How did Earth evolve from a cloud of dust into a planet with oxygen in the atmosphere, ocean basins, and vegetated continents? (EOS 2130 How to Build a Habitable Planet)
• What happens when continents collide, ocean basins open, and volcanoes erupt? (EOS 2145 Plate Tectonics)
• How and why do rocks break, bend, and buckle? (EOS 2225 Structural Geology and Analysis)
• How do water, ice, and gravity carve landscapes and build landforms? How do humans interact with and reshape landscapes? (EOS 2345 Geomorphology: Form and Process at the Earth's Surface)
• How are environmental benefits and harms distributed among different groups of people? 人类活动如何改变地球系统?这些活动产生了什么反馈? (EOS 2385 Environmental Justice and Earth Surface Processes)
• 我们如何利用地球上空750公里的卫星收集的数据来了解海洋的过程? (EOS 2550 Satellite Remote Sensing of the Ocean)
• 海洋是如何影响地球气候的?随着气候的变化，海洋又是如何变化的? (EOS 2585 Ocean and Climate), (EOS 2515 Paleoceanography),(EOS 2625 Ocean Acidification)
• The Arctic and Antarctic regions are both cold and icy; how are they similar and how are they different and why are they so sensitive to climate change? (EOS 2530 Poles Apart: Exploration of Earth’s High Latitudes)
• 为什么缅因湾是世界上生物最丰富的海洋生态系统之一? (EOS 2565 Coastal Oceanography)
• How have carbon dioxide and climate changed over Earth’s history? How can we use this knowledge to understand modern climate change? (EOS 3020 Earth Climate History)
• How does climate drive tectonic processes? How do tectonic processes drive climate? (EOS 3140 Tectonics and Climate)

从追踪有害藻华是如何沿着海岸线发展到了解超级火山是如何在地球深处形成的, studies in EOS open a world of possibilities.
